bugfixes for every release of Megaco. Each release of Megaco
thus constitutes one section in this document. The title of each
section is the version number of Megaco.</p>

<p>Callbacks, when the callback module is unknown (undefined),
results in warning messages. </p>
<p>A race condition scenario. As part of a cancelation operation,
replies with waiting acknowledgements is cancelled. This includes
informing the user (via a call to the handle_trans_ack callback
function). It is possible that at this point the connection data
has been removed, which makes it impossible for megaco to
perform this operation, resulting in the warning message. The
solution is to also store the callback module with the other
reply information, to be used when cleaning up after a
cancelation. </p>
